Been using Solartex with latex paint for many years with great success.
I do use a primer from Benjamin Moore called fresh start. (gives greatly
improved adhesion) Then I spray my color followed by a clear poly top coat.
My planes see lots of air time and latex doesn't last forever . Usually after
5 seasons or so I end up recovering or repainting.
Only warning I have is try to avoid using the color yellow. Yellow is very
transparent and must be applied over white.
Which means adding more paint layers.
More paint = more weight.

Roby
